# CUDA Voxel Processing - Quick Start Guide
|
||
|
||
## Installation (5 minutes)
|
||
|
||
```bash
|
||
# 1. Navigate to project directory
|
||
cd /home/user/Pixeltovoxelprojector
|
||
|
||
# 2. Build CUDA module
|
||
./cuda/build.sh
|
||
|
||
# 3. Verify installation
|
||
python3 -c "import voxel_cuda; voxel_cuda.print_device_info()"
|
||
```
|
||
|
||
## Basic Usage (10 lines of code)
|
||
|
||
```python
|
||
import voxel_cuda
|
||
import numpy as np
|
||
|
||
# Create GPU voxel grid (500³ voxels)
|
||
grid = voxel_cuda.VoxelGridGPU(500, 6.0, np.array([0, 0, 500], dtype=np.float32))
|
||
|
||
# Setup 10 camera streams
|
||
mgr = voxel_cuda.CameraStreamManager(10)
|
||
|
||
# Configure cameras (example for camera 0)
|
||
position = np.array([1000.0, 0.0, 0.0], dtype=np.float32)
|
||
rotation = np.eye(3, dtype=np.float32).flatten()
|
||
mgr.set_camera(0, position, rotation, fov_rad=1.0, width=7680, height=4320)
|
||
|
||
# Process frames (8K resolution)
|
||
prev_frames = np.zeros((10, 4320, 7680), dtype=np.float32)
|
||
curr_frames = np.random.rand(10, 4320, 7680).astype(np.float32) * 255
|
||
mgr.process_frames(prev_frames, curr_frames, grid, motion_threshold=2.0)
|
||
|
||
# Get results
|
||
voxel_data = grid.to_host() # Returns numpy array (500, 500, 500)
|
||
```
|
||
|
||
## Examples

||
```bash
|
||
python3 cuda/example_cuda_usage.py --8k --num-cameras 10 --frames 100 --save-output
|
||
```
|
||
|
||

||
## Troubleshooting
|
||
|
||
**Module not found after build**
|
||
```bash
|
||
# Add to Python path
|
||
export PYTHONPATH=/home/user/Pixeltovoxelprojector:$PYTHONPATH
|
||
```
|
||
|
||
**CUDA out of memory**
|
||
```python
|
||
# Reduce voxel grid size
|
||
grid = voxel_cuda.VoxelGridGPU(256, 6.0, grid_center) # 256³ instead of 500³
|
||
```
|
||
|
||
**Slow performance**
|
||
```python
|
||
# Check GPU is being used
|
||
voxel_cuda.print_device_info()
|
||
|
||
# Optimize for 8K
|
||
voxel_cuda.optimize_for_8k()
|
||
```
|
||
|
||
## Next Steps
|
||
|
||
1. Read `/cuda/README.md` for detailed documentation
|
||
2. Review `/cuda/IMPLEMENTATION_SUMMARY.md` for technical details
|
||
3. Modify `/cuda/example_cuda_usage.py` for your use case
|
||
4. Integrate into existing pipeline (compatible with `voxelmotionviewer.py`)
|
||
